Using LO 100 16

If you cannot access the login page, you must verify the SSL encryption level of your browser is set to 128

bits. The SSL encryption level within the management processor is set to 128 bits and cannot be changed.

The browser and management processor encryption levels must be the same.

To use the preinstalled certificate, enter https://ipaddress in the address line of the browser, which

uses SSL-encrypted communication. Enter http://ipaddress to use non-SSL encrypted communication.

Using SSH

SSH is a telnet-like program for logging in to and executing commands on a remote machine, which

includes security with authentication, encryption, and data integrity features. The Lights-Out 100 remote

management processor can support simultaneous access from two SSH clients. After SSH is connected

and authenticated, the command line interface is available. LO 100 supports two simultaneous SSH

connections. SSH is an advanced feature available by installing the Lights-Out 100c Remote Management

Card.

LO 100 supports the following protocols:

• SSH protocol version 2

• PuTTY 0.54 or later

• OpenSSH

LO 100 comes preinstalled with a certificate. To install a user-specific certificate, see the one-time

"Importing a certificate (on page 43)" setup procedure.

Using the SSH utility

When using a SSH utility to connect to a server for the first time, the utility prompts you to accept the

server public key, sometimes referred to as a host key. Accepting this key authorizes the utility to store a

copy of the public key in its own database. The utility recognizes the server when future connections are

attempted by comparing the public key to the one stored in its database.

NOTE: Logging in to an SSH session could take up to 90 seconds. Depending on the client

used, you might not see on-screen activity during this time.

To access the remote management processor using SSH:

1. Open an SSH window.

2. When prompted, enter the IP address, login name, and password.

Using the PuTTY utility

PuTTY 0.54 is a terminal emulation product that includes support for telnet and the SSH protocol. PuTTY

0.54 is available for download from the Internet.

• To start a PuTTY session, double-click the PuTTY icon in the directory in which PuTTY is installed.

• To start a PuTTY session from the command line:

o To start a connection to a server called host, enter:

putty.exe [-ssh | -telnet | -rlogin | -raw] [user@]host

o For telnet sessions, you can also enter the following alternative syntax:

putty.exe telnet://host[:port]/

1 2 ... 11 12 13 14 15 16 17 18 19 20 21 ... 51 52
